I can't comment on the specifics, but I bought a cheap Speex  wireless
router off eBay for my mum. It worked fine with my Dell laptop, but
her Thinkpad never kept the connection up.

I replaced the router with a Zyxel model, and everything works fine
now. This was all under XP, so there should have been no driver
issues.

So yes - wireless devices can be incompatible with each other. As for
which device is causing the problem - the USB adapter should be the
cheapest to replace, so I'd try that first.
